I also take adderall, along with the anti-depressent, Paxil. I do not notice, daily, the paxil, but adderall has caused quite an impression. After taking it for almost six months, I know that I love it when I am on it, but I have extreme psychological lows when I choose not to take it. I don't feel a real coantinuity in my life without it. That frightens me immensely. To sleep do not take it six hours before bed or maybe have a drink also before bed. After two months I was able to sleep no matter when I took it. Have you ever took it with cocaine and if so, how did you feel? Please respond to tell me you received the message. -Joe
